19 Claims.

YThe present invention relates to road joint installers, and aims .to provide a simple .and convenient means for installing joint strips, members or formsin a concrete road under construction. A further object of the linvention is the provision of novel means Yfor guiding the joint strips, members or forms down into theplastic concrete in order that such strip s,members or forms Ymay be accurately positioned d With `the foregoing and other objects in View, which will be apparent as ythe description proceeds, the invention'residesin the construction and arrangement of parts as hereinafter de- I scribed and claimed, it being -understood that changes can be made within the scope of what is claimed, vwithout departing from the spirit of the invention.

The invention is illustrated in the accompanying drawings, wherein-- Figure l is a-plan vview of amovablebridge or vframerernbodyingV theimprovements.v l Fig. 2 isv a perspective view illustrating ,two pairs .of guide members.

-3 .is a perspectiveY view similar lto Fig. 2 illustrating a modification.

Fig. 4 is a similar perspective view amore simple construction.

Fig. 5 is a side elevation of a device to be used in connection withthe. joint installer for cutting va groove or slot in the concrete.

Fig.: 6 is a front view ofsaidf device.

Fig. .7 is a side elevation of a modified groove or slot cutting device.

f A` bridge or frame .1- haswheels 2 to roll 'on the -side rails or forms 3 betwe'en which theroadis built, and said bridge has transverse and longitudinal pairs of spaced platforms i` and- 5, respectively, on which-the workmen aresupported whileinstalling and nishing the joints.

Pairs of guide members or `arms'6 are disposed between each pair of platforms andhave sleeves l rotatable and slidable on spindles 8 `normally illustrating form of vertical position and having their lower ends -secured toangle irons or bars 9 seatable on the adjacent edge portions of the platforms, said angle irons or bars being hinged, as atvlO, on the platforms to swing upwardly andl outwardlyfor raising the arms 6 offtheV concrete. 1

` .The arms v6p-have"parallel vertical edgesand terminate at the lower ends of said edges in spurs 11, which may entervtheconcrete at'the opposite sides of the joint or which may7 be supported abovethe surface ofthe concrete by means Aof nuts l2 threaded on the spindles s andsupporting the sleeves 7. Nuts 13 or other stops are engaged in the road or pavement.

on the upper ends of the spindles g3, .to prevent the arms 6 from falling off said spindles'. The nuts 13 may also bensed for `clamping the sleeves 7 in place.

OneY set of arms forms 5 for installing longitudinal"joints, and two sets `of arms are v provided between the plat'- forms 4', one' at eachside of the longitudinal joint line, for installing the transverse joints, which may either be in alinement, as' seen in Fig.

l, or in staggered relation.V

When the' bars y9 arefswung vinwardlyjag'ailst fthe inner edges ofthe platforms, and the arms 6 positioned the transverse and longitudinal joint strips, members or forms 14 and'15, respectively, maybe positioned between the arms andthen forceddownwardlyinto' the plastic concrete. The concrete may be previously cut, grobved or otherwise prepared so as to receive the strips. strips may be of premolded material, metal, or 'other suitable material, or forms may be. proivided to be removed grooves which 'may be sealing material. The arms 6 may be swung upwardly outof the v way between the platforms, with Vthe bars9, to enable thejoints to beconveniently nisheda'nd theconc'rete edged along the jointr strips orforms.

vfilled with tar,jor other vlhearrns 6 may also be moved vvertically on -th'e 'spindles 8', for purpose of.' a'djuStnient,"and tjrei'r'love' saidarms from the concrete after .the strips Yare i'njpl'ace`. v Rams Vory other implementsmay be employed to force' the strips down intotlie'con'crete.r

Fig. y3 illu"trates horizohtal'rods 6a mounted Vforslidil'lg and rotary movements in bearings 8a secured [on the angle' ironsor f adjacent, ends of said 4 rodsv lwhich may 'the joint. strip or form down into the c'on'crete. Said' fingers may" enter the concrete or may lbe spaced above same, and the rods 6a.y are maintained in their adjusted positions by nuts 12a have fingers 11a,

6 is provided between the yplat- The be turned downwardly jfor guiding Y subsequentlyy to provide l sli bars 9a, andthe thereon bearing .against the ends ofthe' bearf ings 8d, but permitting' the rods to rotate so' that @the fingers 11a' may be "turned upwardly away fromfth. concrete kto permit the surface' of the concrete tobefioated or trowelled, and the edges of tliejoint finished;

Fig. 4 illustrates a simple forni wherein lthe angle irons or bars 9bhave the guilde members .6b Awelded or otherwise secured thereto and 'etending toward oneanother to guide theljint ,strip or formV downwardly between them'.r

Sand 6 illustrate a device adpted'to move between the parallel platforms for cutting a groove or slot in the plastic concrete. The device comprises a cutter disk 20 movable in a slot 21 of a guide plate 22 that is disposed on the plastic concrete with the slot extending along the line of the joint, to guide said disk along said line.

The disk 20 is secured on a shaft 23 mounted in a yoke 24, and wheels or rollers 25 are provided to roll on the plate 22 for supporting the disk at the desired depth in the concrete. The wheels 25 are mounted in the lower bifurcated ends of Vertical rods 26 slidably connected with the yoke 24, and adjusted by means of nuts 27 threaded on said rods and swivelled to the yoke, thereby enabling the yoke to be adjusted upwardly and downwardly to regulate the depth of the cut made by the disk.

A handle 28 is connected to the yoke for moving the device along the slot 2l., and the device is preferably vibrated in order that the disk will cut through the plastic concrete more readily. To vibrate the yoke an engine 29 having an offbalanced iiy wheel is mounted on the yoke, or any other suitable means may be employed.

When the arms or guide members are swung out of the way, the groove cutting device may be moved between the parallel platforms, and the plate 22 may be placed on the concrete below the space between the platforms to guide the disk 20. The slot or groove may thus be cut in the concrete to receive the joint strip or form.

Fig. 7 illustrates a modied form of groove cutting device, comprising the cutter disk 20a mounted on the shaft 23a on which the yoke 24a isY mounted.

A handle 28a is secured to said yoke, and an engine 29a. having an off-balanced flywheel is Vmounted on said yoke to vibrate the disk.V

A float 36a is trailed from the shaft 23a by the links 31a, and is connected to the handle 28a by the braces 32a.

Said loat has a depending blade 33a to follow the disk 20a and form the groove or slot to receive the joint strip, material or form. The oat Sea smooths off the surface of the concrete at the opposite sides of the groove.
